LED Drivers

ST offers a large portfolio of energy-efficient
DC/DC powered LED drivers for general lighting, display LED backlighting, automotive exterior and interior lighting ,RGB and monochromatic
LED drivers for signage and traffic signals.
Ideal for both parallel and series configurations, they enable high-efficiency, high-current accuracy, low-noise and small-size solutions. Topologies include buck regulator LED drivers, boost regulator LED drivers, offline LED drivers, linear
LED supply, programmable multi-channels with high dimming capability.

Best-in-class power factor, efficiency, and reliability for LED lighting

Operating directly from the rectified mains, ST’s
HVLED001A offline controller for LED lighting with constant-voltage primary-sensing, uniquely integrates both high- and low-voltage circuitry on the same chip, eliminating the cost of external high-voltage circuitry. The high power factor (>0.9), low total harmonic distortion (<10%), and high power-conversion efficiency (>90%) ensure compliance with the most stringent lighting standards in an efficient, compact, and cost-effective solution.
